Flex10 VC LACP Configurations

Flex10 VC LACP Configurations

Hello,

 

I've two stacked VC in a shared domain single enclosure, and there are two uplinks from each VC connected to HP A5120 SWs with IRF enabled like this.

 

VC01 X3 uplink >>>> HP A5120 SW01 XG1/1/1

VC01 X4 uplink >>>> HP A5120 SW02 XG1/1/1

 

VC02 X3 uplink >>>> HP A5120 SW01 XG1/1/2

VC02 X4 uplink >>>> HP A5120 SW02 XG1/1/2

 

The HP A5120 Switches are configured with IRF enabled:

IRF Port1: XG1/2/1 & XG1/2/2

IRF Port1: XG2/2/1 & XG2/2/2

 

 

The following uplinks on the HP IRF SWs are configured with static link aggregation "XG1/2/1 & XG1/2/2 & XG2/2/1 & XG2/2/2"

 

I've issues in communication between the blades behind the VC & servers behind the HP A5120 SWs.

 

On The VC domain, I see different LAG ID on these shared uplink sets:

 

Bay1 X3   25

Bay1 X4   24

Bay2 X3   26

Bay1 X4   25

 

 

AFAIK, these ports should have the same LAG ID, so i am thinking that this might be the problem, any idea why the LAG IDs are different?

 

could it because i am using static link aggr. instead of LACP?

 

any ideas will be much appreciated.

Re: Flex10 VC LACP Configurations

your cabling looks good. LAG ID should be the same for 2 ports on the same VC module.

 

did you ever take a look at VC/IRF integration guide on configuration and show verfication? you can find the pdf file link off my blog VC bookmark lists.
